With personalities as notable as Talk Radio's fictional Barry Champlain, the Broadway revival welcomes Rev. Al Sharpton and Michael Musto for talkback sessions with members of the cast.

Activist Sharpton and Village Voice columnist Musto will take the stage of the Longacre Theatre May 15 and May 16, respectively, following the 8 PM performance of the Broadway production.

Tony Award winner Liev Schreiber stars in Talk Radio, which began previews on Broadway Feb. 15 at the Longacre and opened March 11. Robert Falls directs the Eric Bogosian play.

Richards, Jerry Frankel and JAM Theatricals produce the Broadway run of Talk Radio, which follows an acid-tongued, late-night talk-show host whose program is about to be picked up for national syndication.

Filling out the characters who live in the world of talk-show host character Barry Champlain (Schreiber) are Peter Hermann ("Law & Order: Special Victims Unit" and "United 93") as producer Dan Woodruff, Stephanie March ("30 Rock" and "SVU") as producer/love interest Linda MacArthur and Michael Laurence (The Rainmaker at the Arena) as friend/foil Stu Noonan.

Sebastian Stan ("The Covenant") plays a young punk caller, along with Christine Pedi (Little Me, Forbidden Broadway), Barbara Rosenblatt (The Secret Garden), Adam Sietz (Barefoot in the Park), Marc Thompson, Cornell Womack (On Golden Pond), Christy Pusz, Oliver Vaquer and Kit Williamson, who play a number of characters on the radio show.
